3.4 HFU-U (BK)/(WH) Unit (Handsfree Unit)
The handsfree unit provides full-duplex handsfree communication.  Large
areas may cause poor full-duplex operation. This unit comes with the
handsfree adapter and an external microphone. With terminal upside
down, facing from the bottom of the open cover, install this unit in
Telephone Slot 1.  
3.4.1 Installing an HFU-U (BK)/(WH) Unit on a Telephone
Refer to 3.2.3 Installing an ADA-U Unit on an Electra Elite
Telephone on page 5-11. The instructions for installing these
units are the same.
3.4.2 Installing the External Microphone
An external microphone can be installed on the HFU-U (BK)/
(WH)  Unit.  These instructions apply to the external microphone
obtained from NEC.  This microphone is equipped with a mute
button.

3.5 CTA-U Unit  (Computer Telephony Application)
Computer Telephony Application allows an Electra Elite telephone to be
connected to a PC.  The PC can then be used to perform all of the
functions of the telephone by using a TAPI-compatible application
software.


The CTA-U Unit requires system software version 2.0.

Full Duplex: In some large areas or noisy locations half duplex should be
used. There are limits to the echo canceling ability of the HFU-U.

Half Duplex:  If voice clipping occurs, use a lower decibel setting.

Telephone Programming
 
SECTION  1 INTRODUCTION
When the system is initially installed, it is fully operational with the preset default
settings.  Users can customize the system by changing system programming values
using either telephone programming or PC programming.  This chapter provides
detailed instructions for programming from a telephone.
Telephone programming is designed primarily for experienced users.
Therefore, if you are a first-time user, we strongly recommend that you use PC
programming instead of telephone programming. 
It should be noted that only one telephone can be in programming mode at a time.  If
another telephone user attempts to access programming mode, that telephone is
blocked from entering programming mode.  
The following InfoSet and Electra Elite telephone types can be used as programming
telephones.  

DTB-16D-1(BK)/(WH) TEL

DTU-16D-2(BK)/(WH) TEL

DTU-32D-2(BK)/(WH) TEL

Only telephone ports 1 and 2 (normally extensions 10 or 11) can be used to
enter telephone program mode.
SECTION 2ENTERING PROGRAMMING MODE
Once you have entered into programming mode you can access the various
programming functions by either using the navigational keys or by manually entering
the function number (e.g., 001-1, 002, 220, etc.).  The function number provides
access to the area you want to program.  Table 6-1 Navigational Keys for Telephone
Programming provides a list of keys you can use to navigate the system.  Table 6-2
Programming Functions Quick Reference Chart provides a complete list of all of the
programming functions. 
To program the system using a telephone, you must first enter programming mode.

3. Dial         
        .  The display shows the information for function number
000-1.        
2.1 Programming Guidelines
When programming you should understand the following:

The telephone display indicates the function number, function group
name and default settings. 

When function numbers are grouped (e.g., 001-1 ~ 001-9), all of the
function numbers are displayed at the same time.  To change
between the default value and the alternate value, press the dial pad
key that corresponds to the last digit of the function number you are
changing.  
For example:  
When you access the function number for 001-1~001-9.  The system
displays:       
If you want to change the programming value for Function 001-4,
press   
  on the dial pad.  When “
appears on the display, you
have changed to the alternate programming value for that function.
The default value is displayed if this is the first time you are using the
system.  If the system has been previously programmed, the
alternate value may be displayed instead of the default value.  It is
important to note that the series of numbers is displayed in
descending order (987654321).

The following navigational keys are used.  Note that the Electra Elite
telephones do not have a SPD key.  The InfoSet telephones use the
 

 and  keys to perform many of the same functions that
the

key does on the Electra Elite telephones.  Throughout this
chapter any differences are noted where necessary.

The line keys are numbered differently for the InfoSet and Electra
Elite telephones.  The diagram below illustrates these differences.  It
is important to keep these differences in mind when programming.  
Typically, line keys 1~4 are used for trunk line assignment.  However,
any unused line keys can be assigned as one-touch/feature access
keys.

SECTION 3PROGRAMMING FUNCTIONS
The table provides a complete list of all of the programming functions.  These are
listed in order by function number. The table consists of four columns, a brief
explanation of each column is listed below.

Function Number
Lists the number used by the system to access the programming functions.

Function Name/Telephone Display
Lists the function name and shows how the function appears in the display of
the telephone.  Since there is limited space in the telephone display, the
functions are abbreviated and will not match the function name.  To
distinguish the function name from the telephone display, the following font is
used to indicate the display: 
 	
 
.  The telephone display
typically consists of two lines. The first line is the abbreviation and the
second line is the default setting.  If your system has been previously
programmed, the number on your display may be different from the one
provided in the table.

Description
Provides a brief explanation of the function.

Programming Values
Lists the programmable options for the function.  Note that the default values
are displayed in bold typeface.
